Bug Description

Samba 4.7.4 and below has an unfortunate upgrade bug

https://bugzilla.samba.org/show_bug.cgi?id=13228

See the release notes for Samba 4.7.5

https://www.samba.org/samba/history/samba-4.7.5.html

Please do not ship Samba 4.7.4 in Ubuntu 18.04, instead given the security release due tomorrow, ship 4.7.6 with both the security fix and this fixed.

Thanks!
